With these pinions the teeth on the on the dials 2. In this class of registers it is under side of the rack-bars 6 engage. Each essential that means be provided for resetting pinion 5 has attached wit a ratchet-wheel 7, the register-shafts and dials 2 to zero. To and the two wheels revolve freely upon the accomplish this quickly and accurately, there is employed a handle 20, secured to a short shaft 21, journaled in the frame 1, said shaft carrying a gear-wheel 22, engaging a rackbar 23, riding on and controlling a springactuated rack -bar 24, located. immediately under the driven rack-bar 23, and the teeth of said rack-bar 24 adapted to engage a series of mutilated pinions 25, secured to the register-shafts 4. hen the register-shafts are in such position that the dials thereon indicate zero, the mutilated pinions 25 will be in the position shown by the first five shafts counting from the left in Fig. 2that is, the mutilated portion of the pinions will be directly under the rack-bar 24 and longitudinal movement of said bar will not affect the pinions; but presuming the register-shafts to have been rotated as shown by the two righthand pinions, Fig. 2, the spring-actuated rack-bar 24 when forced downward into engagement with the pinions, Fig. 2, and given a longitudinal movement by the turning of the handle 20, gear 22, and rack-bar 23 the pinions that have been engaged by said rackbar will be reset to zerothat is, rotated un til the mutilated portions of each pinion is under the raelrbar. After the above operation the rack-bar is free to return to its initial position without engaging the pinions.

The under or pinion-engaging rack-bar 24 is controlled in its longitudinal movement by the rack-bar 23, which rests on the top of the rack-bar 24 and is held in position thereon by engaging the upturned ends 26 and 27 of the rack-bar 24. In a recess 28 in the rackbar 24 is secured a spring 29, that exerts pressure against the two rack-bars and tends to force them apart when they are operated to reset the register-shafts. In the frame 1 are slots 30 and 31, adapted to receive and guide the rack-bars. The lower rack-bar 24 is provided at each end thereof with projecting camplates 33, adapted to engage with corresponding cam-plates 34, secured to the frame 1 of the machine. Normally these cam-plates are in the position shown in Fig. 2-that is, the cams 33 rest on the tops of cams 34, thereby freeing the rack-bar 24 from engagement with the pinions and permitting the register-shafts to be freely rotated. hen the gear 22 is retated by the handle 20, the rack-bar 23 will be moved longitudinally, carrying with it the rack-bar 24. When the rack-bar 24 has moved a suficient distance to permit the cam 33 to ride down the inclined edges of the camplates 34, the said rack-bar 24 will be given a lateral thrust by the spring 29 and moved downward into engagement with the pinions 25, that have been previously operated by the register meansthat is, rotated so that their teeth will be engaged by the teeth of the racl bar. After the rack-bars have been forced apart and moved longitudinally to reset the register-shafts to Zero, Fig. 3, the gear 22 is given a reverse rotation to move the rack-bar 23 back to its initial position, carrying with it the rack-bar 24. On the return movement of the rack-bars the cams 33 on the rack-bar 24 ride up the inclined surfaces of cam-plates 34 and lift the rack-bar 24 sufiiciently far to permit the pinions to turn freely in the registering operation. The spring 29 will be compressed by reason of its engagement with rackbar 23, when the rack-bar 24 is moved into the position shown in Fig. 2.

The operation of resetting the register shafts and dials to zero is accomplished by turning the handle 20, in turn rotating the gear 22, that meshes with the rack-bar 23, giving said rack-bar a longitudinal movement, carrying with it the rack-bar 24, until the inclined edges of the cams 33 and 34 are in position to permit the spring 29 to give the rackbar 24 a lateral thrust that brings it into mesh with such of the mutilated pinions as have been previously operated by the register means. Continued longitudinal movement of the rack-bars will reset all the register-shafts to zero. When the pinions are reset to zero, the mutilated portions thereof are directly under rack-bar 24, so that a reverse rotation of the handle 20 will operate the rack-bar 23 to control and return the rack-bar 24 to its initial position without engaging the pinions.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. The combination of registering mechanism, a resetting device for resetting the registering mechanism at zero, composed of two members adjustable on each other, one member adapted to engage with or be separated from the registering mechanism and the other member adapted to engage with the driving mechanism, and means for adjusting the two members of the resetting device upon each other so as to cause one member to engage with or be separated from the registering mechanism.

2. The combination of registering mechanism, a resetting device for resetting the registering mechanism at Zero, composed of two members adjustable on each other, one member adapted to engage with or be separated from the registering mechanism and the other member adapted to engage with the driving mechanism, and means for yieldingly moving one of the two members into engagement with the registering mechanism and positive means for moving it out of engagement With said registering mechanism.

3. The combination of registering mechanism, a resetting device for resetting the registering mechanism at zero, composed of two members adjustable on each other, one member adapted to engage with or be separated from the registering mechanism and the other member adapted to engage with the driving mechanism, and a spring located between the two members of the resetting device for yieldingly moving one of the two members into engagement w1th the registering mechanism,

and positive means for throwing it out of engagement with said registering mechanism.

4. The combination of registering mechanism, a plurality of registering devices, a resetting device for resetting the registering devices at zero, composed of two members adjustable on each other, one member adapted to engage with or be separated from the registering devices, and the other member adapted to engage with the driving mechanism, and means for adjusting the two members of the resettingdevice upon each other so as to cause one member to engage with or be separated from the registering devices when said registering devices are at other than the zero position.

5. The combination of registering mechanism, a plurality of registering devices, a resetting device for resetting the registering devices at zero, composed of two members adjustable on each other, one member adapted to engage with or be separated from the registering devices, and the other member adapted to engage with the driving mechanism, means for yieldingly moving one of the .two members into engagement with the registering devices when said registering devices are at other than Zero position, and positive means for restoring said member to its normal position of disengagement from the registering devices after the registering devices have been reset at zero.

6. In a register, the combination of a plurality of register-shafts, means for operating the same, pinions on the register-shafts, rackbars, one of said rack-bars capable of lateral movement, means for operating said rackbars, the laterally-movable rack-bar normally out of engagement with the pinions, and means for laterally moving said rack-bar into and out of engagement with the pinions.

7. In a register, the combination of a plurality of register-shafts, means for operating the same, pinions secured thereon, a rack-bar, capable of lateral and longitudinal movement and operatively engaging the pinions, a rackbar operatively connected with and controlling the movement of said rack-bar, and means for operating said bars, for the purpose explained.
